14. A manager of a local fast food restaurant wants to determine the average amount of time it takes from when a customer enters the drive-through line until they receive their order, regardless of the time of the day and the day of the week. That is, he would like to know the true average drive-through wait time for all his customers. Which of the following methods would be most likely to estimate the desired parameter with low bias and low variability?
(A)Select a random sample of 100 customers over a period of one month, determine each selected customer’s wait time, then compute the average wait time for all 100 customers.
(B)Select a random sample of 100 customers over a weekend, determine each selected customer’s wait time, then compute the average wait time for all 500 customers.
(C) Select a random sample of 500 customers on a randomly selected weekday, determine each selected customer’s wait time, then compute the average wait time for all 500 customers.
(D)Select a random sample of 500 customers over a weekend, determine each selected customer’s wait time, then compute the average wait time for all 500 customers.
(E) Select a random sample of 500 customers over a period of one month, determine each selected customer’s wait time, then compute the average wait time for all 500 customers.
Answer:E
Explanation:
Select a random sample of 500 customers over a period of one month, determine each selected customer’s wait time, then compute the average wait time for all 500 customers.
Why sampling is important?Sampling saves money by allowing researchers to gather the same answers from a sample that they would receive from the population.
Select a random sample of 500 customers over a period of one month, determine each selected customer’s wait time, then compute the average wait time for all 500 customers. it will help in the improve to deduce the time and might be get idea so that costumer will not wait rather than ideal time.

PLEASE PLEASE HELP:: The scoop of an excavator holds 26 ft3 of sand. If the capacity of a freight car is 39 tons of sand and we know that 1 ft3 of sand weighs 0.5 tons, how many freight cars can be filled with 120 loads?
Answer:
40
Explanation:
Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion
26/x=1/0.5
If you simplify it, you should get x=13
Now that we know 26 ft3 of sand = 13 tons, we should multiply it with 120 number of loads
13*120=1560
Then, we have to divide 1560 by 39 which should give your answer 40
Hope this works!
Freight cars can be filled with 120 loads is 40
How is load percentage calculated?
The load factor percentage is derived by dividing the total kilowatt-hours (kWh) consumed in a designated period by the product of the maximum demand in kilowatts (kW) and the number of hours in the period.
Since we know that 1 ft3 of sand = 0.5 tons, we can make a proportion

James was the lead in the school play. It was opening night. Mr. Ramirez, the director, asked James if he was ready to go on and reminded him about a few last-minute changes in the script. A number of thoughts and feelings came over James as the curtain went up. James became anxious when he saw all the faces of the audience members. Then he saw his mother, who is a professional actress, sitting in the front row. James could not relax. At that instant, he saw his psychology teacher in the audience. He knew that he needed to use the concepts learned in her class to make sense of these thoughts, feelings, and surroundings.
Describe how each of the following concepts might help James give a strong performance.
State-dependent memory
Arousal theory
Positive reinforcement
Selective attention
Imagery
Social facilitation
Sensory adaptation
Answer:
Check below for the answer and explanations
Explanation:
State-dependent memory: is the process of remembering things because they happen when you were in a state that is similar to your current state. Before the opening night, James would have gone through series of rehearsals, it will be easy for him to recollect the things he said or did during the rehearsal and apply same in the opening night.
Arousal theory: This theory explains that people tend to have a better performance when they are psychologically motivated. James felt motivated when he saw his psychology teacher in the audience. This motivation will enhance is performance.
Positive reinforcement: James motivated himself by wanting to use the concept learnt in his psychology class to have a positive thought about the surrounding atmosphere. This is a positive reinforcement because James felt motivated after this consideration.
Selective attention: This is the process of focusing only on relevant information or object. James paid more attention to those whose presence can aid his performance. He did not have to set his gaze on every member of the audience.
Imagery: In this context, imagery is the use of mental, imaginary pictures to influence one's thought process. As James is on the stage, there should be a mental picture of when he was taking similar roles during the rehearsals, this will help him perform better.
Social facilitation: The presence of a large audience aids the performance of some people. They tend to perform better in the presence of crowd. James can utilize the advantage of the cheers and the applause he receives from the audience for a better performance.
Sensory adaptation: As James spends more time outside performing, his senses tend to adapt to that atmosphere and the initial fright and timidity will disappear. At this stage, he begins to perform incredibly well.
State dependence memory is the process of remembering things due to what happened. They take place when you are in a state similar to the current state.
Arousal theory suggests that people are driven to take actions that tend to maintain an optimal level of psychological arousal. Selective attention is a process that allows the individual to focus on a specific topic, or input for further processing. Imagery is any visual figurative language that evokes a mental image. Social facilitation is the improvement or the decrease of performance when working together with other people. Sensory adaptation is the reduction of the sensitivity to stimus after long exposure.Learn more about the lead in the school play. It was opening night.

Tara mows lawns as a summer job. She
charges $9.50 for each lawn plus $2.50 for
every hour she works. The gasoline she needs
to mow an average lawn costs $1.85. Write an
expression for the profit Tara makes from
cutting a single lawn.
Answer:
9.50+(2.50x)1.85
Explanation:
I think this might be it because you don't really get the time she works for a lawn
Answer:
7.65 + 2.50h
Explanation:
The original expression for finding her profit is:
($9.50x + $2.50h) - 1.85x
x being the number of lawns she mows
h being the number of hours she works
If she were to only mow one lawn, the expression would be:
($9.50(1) + $2.50h) - 1.85(1)
h remains constant because we do not know the number of hours she works for
The above expression simplified:
($9.50 + $2.50h) - 1.85
So, I do... $9.50 - 1.85 to get...
$7.65 +$2.50h
